Nginx installation configuration + Clear Cache module installation

After a period of use, found nginx in the concurrency and load capacity is indeed superior to Apache, now the majority of sites from Apache to Nginx. The following are some simple installation configurations for Nginx.

Environment

Operating systems: CentOS, RedHat

IP Address: 192.168.1.202

Download Package

# Mkdir/usr/local/src/tarbag

# Mkdir/usr/local/src/software

# cd/usr/local/src/tarbag/

Nginx

# wget http://www.nginx.org/download/nginx-1.0.6.tar.gz

Nginx Cache purge Module (optional)

# wget http://labs.frickle.com/files/ngx_cache_purge-1.3.tar.gz

Compiling the installation

# cd/usr/local/src/tarbag/

# TAR-XZVF Nginx-1.0.6.tar.gz-c/usr/local/src/software

# TAR-XZVF Ngx_cache_purge-1.3.tar.gz-c/usr/local/src/software

# cd/usr/local/src/software/

#./configure \

--prefix=/usr/local/nginx-1.0.6 \ # Installation path

--with-http_stub_status_module \ # Enable Nginx State module

--with-http_ssl_module \ # Enable SSL module

--with-http_realip_module \ # Enable the Realip module (forwards the user IP to the back-end server)

--add-module=. /ngx_cache_purge-1.3 # Add cache cleanup Extension Module

# make

# make Install

Kernel parameter Optimization

# VI sysctl.conf Add the following configuration

net.ipv4.netfilter.ip_conntrack_tcp_timeout_established = 1800

Net.ipv4.ip_conntrack_max = 16777216 # If default parameters are used, network drops are prone to occur

Net.ipv4.netfilter.ip_conntrack_max = 16777216# Prone to network drops if default parameters are used

Net.ipv4.tcp_max_syn_backlog = 65536

Net.core.netdev_max_backlog = 32768

Net.core.somaxconn = 32768

Net.core.wmem_default = 8388608

Net.core.rmem_default = 8388608

Net.core.rmem_max = 16777216

Net.core.wmem_max = 16777216

Net.ipv4.tcp_timestamps = 0

Net.ipv4.tcp_synack_retries = 2

Net.ipv4.tcp_syn_retries =

Net.ipv4.tcp_tw_recycle = 1

Net.ipv4.tcp_tw_reuse = 1

Net.ipv4.tcp_mem = 94500000 915000000 927000000

Net.ipv4.tcp_max_orphans = 3276800

Net.ipv4.ip_local_port_range = 1024 65535

Configuration takes effect

# sysctl–p

Modify the Iptables startup script to add the Star () function

# Vi/etc/init.d/iptables

/sbin/sysctl-p

Configure the sample site site

Serial number

/www/html/bbs.heytool.com

To modify the Nginx configuration file:

# VI Nginx.conf

User nobody nobody; # run Nginx's owning group and owner

Worker_processes 2; # Open two nginx work process, generally several CPU core write a few

Error_log Logs/error.log Notice; # error log path

PID Logs/nginx.pid; # PID Path

Events {

Worker_connections 1024; # One process can handle 1024 requests at a time

}

HTTP {

Include Mime.types;

Default_type Application/octet-stream;

Log_format Main ' $remote _addr-$remote _user [$time _local] "$request" '

' $status $body _bytes_sent ' $http _referer '

' "$http _user_agent" "$http _x_forwarded_for";

Access_log Logs/access.log Main; # Default Access log path

Sendfile on;

Keepalive_timeout 65; # KeepAlive Supermarket time

# Start configuring a domain name, a server configuration segment typically corresponds to a domain name

server {

Listen 80; #

# Listen on all IP on this machine 80, can also write as 192.168.1.202:80, so that, only listen to 192.168.1.202 on the 80 port

server_name www.heytool.com; # Domain Name

root/www/html/www.heytool.com; # Site root directory (program directory)

Index index.html index.htm; # index File

Location/{# can have multiple location

root/www/html/www.heytool.com; # Site root directory (program directory)

}

Error_page 502 503 504/50x.html;

# define the error page, if it is a 500 error, then return the site root directory 50x.html to the user

Location =/50x.html {

root/www/html/www.heytool.com;

}

}

# Start Configuring Site bbs.heytool.com

server {

Listen 80;

server_name bbs.heytool.com;

root/www/html/bbs.heytool.com;

Index index.html index.htm; # index File

Location/{

root/www/html/bbs.heytool.com;

}

Error_page 502 503 504/50x.html;

Location =/50x.html {

root/www/html/bbs.heytool.com;

}

}

}

Nginx Startup off

#/usr/local/nginx-1.0.6/sbin/nginx//Start Nginx

#/usr/local/nginx-1.0.6/sbin/nginx–t//test nginx configuration file Accuracy

#/usr/local/nginx-1.0.6/sbin/nginx–s Reload//heavy-duty Nginx

#/usr/local/nginx-1.0.6/sbin/nginx–s Stop//off Nginx

Test

To create a test site

# mkdir–p/www/html/www.heytool.com

# mkdir–p/www/html/bbs.heytool.com

# echo "www.heytool.com" >/www/html/www.heytool.com/index.html

# echo "bbs.heytool.com" >/www/html/bbs.heytool.com/index.html

start Nginx

#/usr/local/nginx-1.0.6/sbin/nginx–t//See OK and successful, explain the configuration file no problem

Nginx:the configuration file/usr/local/nginx-1.0.6/conf/nginx.conf syntax is OK

Nginx:configuration file/usr/local/nginx-1.0.6/conf/nginx.conf Test is successful

#/usr/local/nginx-1.0.6/sbin/nginx

Bind hosts, test

Point two domains to 192.168.1.202

192.168.1.202 www.heytool.com

192.168.1.202 bbs.heytool.com

Open www.heytool.com, such as:

Nginx

Open bbs.heytool.com, such as:

Nginx

Complete!!!!
